Abstract

Planar 45° turning mirrors with metal coating, embedded in SU8 polymer waveguides, enable waveguide to vertical mode coupling across a broad range of wavelengths from the visible to IR. The fabrication of these 2.5D structures is achieved using relatively simple grayscale lithography in thin film resists, compatible with standard planar lithography methods. Mirror losses of <1dB are measured from 516 -1630 nm, and direct coupling to single mode fibre is achieved.
